This Snow and Arrow slipper is crafted from 100% organic cotton knit outer and is fully lined with 100% USA grown and milled organic cotton fleece and features a non-slip leather sole. The special elastic ankle is designed to easily go on and gently hug your little one's ankle, but best of all they are going to stay on wiggly feet! Sizes 6m and up have a leather toe kick to protect the slipper from wear and tear. 0-3m and 3-6m slippers do not have leather toe kicks. All slippers are handcrafted in Heber Springs, Arkansas.
